7/19 - The results do not improve with more training data. I then tried to use Yang's code with LSTM. The accuracy rate is still too low, and I'm trying to learn more about LSTM to see how to adjust the parameters.
7/20 - I have not yet figured out how to get Yang's code to run at 60% accuracy as his wiki page says. If I use less labels(5-7 instead of 40) with Christy's code(IndustryClassifierCONDENSED-USETHIS.py), the accuracy rate is around 50%. However, with 40 labels, the accuracy rate is only 25%. With Yang's code, less labels also increases the accuracy rate, but not to 60%.
